Implantation Bleeding

Kaitlyn

I am 7DPO I’ve been having symptoms like sore breasts, hot flashes, mild nausea, and mood swings. My period is due in 1 week. I thought I might possibly be pregnant but today I started having light brown discharge when I wipe. I usually get it before my period comes but usually not this early on. Could it be implantation bleeding or is it just that my period is about to come?
